S2·E10 Celestial Skirmish

Natsu is after Erza and Jellal and Lucy and Hibiki and Carla and Wendy are after him. As they search for him Natsu appears to find Gray unconsious in a stream. Natsu helps him out but Gray is actually two spirits from Oracien Seis. Gemi and Mini twin spirits of Gemini. They can copy anyone and know exactly what their thoughts are and copy their magical power. Gray (Gemini) undoes and anchor on a raft which Natsu is on and Natsu becomes sea-sick. Lucy and Hibiki arrive and see Gray is about to kill Natsu. They assume he has fallen for the darkness of Nirvanna. When they try to stop him Gemini takes on the form of Lucy then is able to control Saggitarius, who Lucy called out to stop Gray, Saggitaruis shoots at Hibiki making him unable to battle. Then Oracien Seis's Celestial Spirit Wizard appears, Angel. She tells Gemini to stop. Lucy replaces Saggitarius with Aquarius and Angel calls out Scorpio.
